I am working on natural fiber reinforced composites. I had conducted flexural and tensile testing on these composite materials as per the astm standards . I want to know how to validate my results
I think you should make many specimens then get the output data to characterize such material with certain confidence level.
Also, If there were peoples who tested same material ,then you should compare your results with them.
Hi Kumar,
I agree with the last two comments. As recommended by the standard, you should have at least 5 samples for each test condition. In addition, if your data spread is quite wide, you may need more samples then omit the data point(s) separated away from others, but you should keep that you have at least 5 data point for each test condition.
As natural fibers have varying dimensions which are not uniform, at least 10 specimens have to be tested and average taken. Further, the statistical parameter like SD has to be considered for each set of results.
The Rule of Thumb for any test that ends with fracture is to repeat it 30 times, if you have the resources. Then you can analyze the results statistically and fit a distribution, such as Weibull to the data. Good Luck!
How many specimens are required for validation of result? if u have the reference (for minimum requirement specimen) please give it to me.
As i know minimum 5 sample test to be carried out. SD is to be calculate. also some of available Theoretical models can be used for validation.
